IGNITING APPARATUS FOR GAS-ENGINES.

SPECIFICATION forming part of Letters Patent No. 401,204, dated April 9,1889.

Application tiled December 3, 1888. Serial No. 292,505. (No model.)

To all whom it may concern:

Be it known that we, LEWIS C. PARKER and BEAUMONT PARKER, citizens ofthe United States of America, residing at Kansas City, in the county ofJackson and State of Missouri, have invented certain new and usefulImprovements in Igniting Apparatus for Gas- Engines, of which thefollowing is a specification, reference being had therein to theaccompanying drawings.

This invention pertains to certain new and useful improvements ingas-engine ignitors, having reference to that class of devices wherein aportion of the combustible mixture is compressed within the interior ofa pipe or chamber the exterior of which is heated.

The invention comprises the details of construction, combination, andarrangement of parts, substantially as hereinafter fully set forth, andparticularly pointed out in the claims.

In the accompanying drawings, Figure l is shaft.

B is the exhaust-chamber secured to cylinder A, and communicatingtherewith through port b. A valve, t', is disposed in the upper part ofthis exhaust-chamber, so as to open downward and permit the exhaust topass out through an upper opening, b2. This valve is operated at thedesired moment by suitable mechanism of ordinary construction. (Notshown.)

C is a pipe or chamber screwed into the exhaust-chamber B, and throughit is d rau'in the charge of air and gas, a pivote-d valve, C, beingused to prevent backward escape thereof.

The ignition-chamber D consists of ashort pipe or tube secured to aplate or disk, d, which is held to a fianged collar, d', of pipe C bymeans of bolts cl2, a piece of asbestos or other non-conductingmaterial, d3, being interposed between plate d and collar d. A curvedarm or shield, E, projects from the upper part of plate or disk d, andthe same is provided with holes or apertures e for the escape of smokefrom an ordinary burner, e', disposed in close proximity to theignitionchamber D. The shield E serves to coniine the heat around saidchamber, the same being provided with an outer covering of asbestus,E

A valve, E, is designed to iit over the inner open end of chamber D, andthe same is provided with an inclined hole or port, f, extendingtherethrough. The stem f of this valve is projected across pipe C andout through a suitable boxing, f2. This valve, like the exhaustvalve b',is operated at the desired moment by suitable mechanism. (Not shown.)

The operation-is as follows: The piston in starting on itscharging-stroke will draw in a charge of gas and air through pipe C, atwhich time valve E is opened and so remains until the piston has madeabout one-fifth of its next or compression stroke, when said valve isclosed over the ignition-chamber. During a portion of the balance of thecompressionstroke a small jet of the mixture is being forced throughport f into the ignition-chamber and is being quickly heated therein toa high degree. \Vhen the piston reaches the maximum of itscompression-stroke, the valve F is opened and the compressed mixture inpipe C is exploded by coming in contact with the heated mixture in theignition-chamber D and with said chamber. The mixture rushes into thecylinder when the piston makes its power-stroke. At the next or exhauststroke the exhaust-valve Z2 is opened and the products of combustionpermitted to escape.

By reason of the described arrangement the next incoming charge entirelyclears pipe C, the ignition-chamber, and the exhaust-chamber, thussecuring a pure fresh mixture for each successive charge.

Te claim as our inventionl. As an improvement in gas-engines, thecombination, with the inlet pipe or chamber, of the exhaust-chamber andits valve, the ignition-chamber applied to one side of the inlet pipe orchamber, around and out-side the inlet-arm of which is applied a plateor disk, and between which and a second plate is interposed asbestuscovering, together with means for fastening in place the same,substantially as set forth.

IOO

chamber, of the plate or disk secured thereto, the Vinterposed asbestus,the arm or shield' having an asbestus covering, and the seeur- 15ing-bolts, substantially as described.

In testimony whereof We affix our signatures in presence of twoWitnesses.
